Starting in 2014, being sick won’t keep you from getting health coverage. An insurance company can’t turn you down or charge you more because of your condition. It can’t refuse to cover treatment for pre-existing conditions.

This is true even if you have been turned down or refused coverage due to a pre-existing condition in the past.

The only exception is for grandfathered individual health insurance plans–the kind you buy yourself, not through an employer. If you have one of these plans you can switch to a Marketplace plan during open enrollment and get coverage for your pre-existing condition.
